Automatic Transmission Control Module – Subaru (30919AF46B)
The Automatic Transmission Control Module – Subaru (30919AF46B) is a Genuine OEM electronic control unit crafted to manage the operation of Subaru’s automatic and CVT transmissions.

Housed in a sealed, vibration-resistant enclosure, this OEM module withstands engine-bay stressors like thermal cycling, moisture, and mechanical vibration. Subaru’s rigorous OEM testing ensures long-term reliability and precise shift calibration, eliminating harsh engagements or slippage often seen with aftermarket alternatives.
The 30919AF46B is designed as a direct plug-and-play replacement, matching factory travel path, connector type, and mounting bracket. Installation is straightforward: a simple bolt-on swap using standard tools, with no need for wiring modifications, module coding, or calibration. Once installed, the transmission reverts to Subaru’s original shift logic immediately.
